GSMCTRL02 controller expands the intercom capabilities by calling one or more mobile phones of the apartment residents.

Intercom model, call duration, DTMF codes for opening the doors are programmed. Database of the telephone numbers is loaded via FTP.

GSMDU – the universal device which can be used for protection, monitoring and management. For example, automatic phone dialer; communicator with the security panel; remote control for domestic appliances, gate or barrier remote opening; standalone alarm and access control system; etc. It has also built in switching mode power regulator and 12 V battery charger.

The built-in program does all functions as GSMM: sending out alarm or information messages through SMS, calls, voice messages, DTMF, CSD, GPRS; information exchange trough ADEMCO Contact Id protocol; reception of the commands accepted through SMS, DTMF, CSD and GPRS; saving log events in 4MB Data Flash; also controls battery fullness and power availability. This makes the program unique as these characteristics enable it sending the last message until the battery runs completely empty and then the gadget is turned off.

All GSM/GPRS devices can be diagnosed, upgraded and set through GSM.

GSMM – miscellaneous device, which could be used in various ways: safety-alarm , monitoring and control systems. As an example: automatic phone dialer; communicator of alarm receiver; remote control for domestic appliances; remote control for barrier; etc.
